Question

The pascal is actually a very small unit of pressure. To show this, convert 1 Pa = 1 N/m² to lb/ft². Atmosphere pressure at sea level is 14.7 lb/in². How many pascals is this?

Answer 1

pascals is this = 101352.972 Pa

Step-by-step explanation:

given data

Atmosphere pressure at sea level = 14.7 lb/in²

we convert 1 Pa = 1 N/m² to lb/ft²

so we convert here 14.7 lb/in² to pascals

we know that 1 lb/ft² = 47.990172 N/m²

so

1 lb/ft² × ft²/(12in)² = 47.990172 × 144 N/m²

it will be simplyfy

1 lb/ft² = 6894.76 N/m²

so

14.7 lb/in² = 14.7 × 6894.76 N/m²

14.7 lb/in² = 101352.972 Pa
